My lexan window above the front window (1990 mci 102c3 ) started to cup or warp over the last few years and I added silicon at the rubber and the lexan as the lexan would not stay in the rubber.Now that I have time to repair it I removed all the silicon ,cleaned the rubber.But when I tried to reinstall it I could not get the warp out of it and I cracked it . Now I have looked on line at nimco for a new or used one. I will call them on mon. How much will it cost? and is it because of age that the old one warped? Any ideas thanks dave

What about 18 gage satin coat gal. like I used on the skin over the side windows.Its not like you can see through it .Thats were the tv, a/c is. Cut to size paint and install in the rubber used for the lexan? dave

I had the same problem with the overhead window on my 96A3. I put in a piece of alucabond. I had it cut and power pressed into the right shape based upon the old piece of lexan. I love the result and know it won't deteriorate in the UV rays. Plus I have no more water leakage and it is quieter to boot. See if you can find a local sign place or commercial building exterior provider. The alucabond is used on commercial building exteriors and on signs. Mine cost me $90. You will not like the price of a new window!

I replaced my Prevost driver's side lexan dual pane with real glass. Prevost quit using Lexan due to the many problems that comes with it.I would take your lexan panel to an auto glass shop and talk with them. Good Luck Gerry H
